Look into other predictors

read in predictor datasets

• DEM
• rock outcrop
• slope
• soil type ## to do:
• once it is clear which dates are relevant: get wind speed and direction
• terrain-derived data
  • TWI
  • regional microclimate (small depressions, polygon cracks etc)
• distance to lakes and runoff channels
• pH // EC: Pierre
• permafrost data: Bockheim

Crop all predictors to rock outcrop settings

Lakes and streams

Those don’t really look that great… Trying to get some sentinel 2 scenes for detecting lakes and streams by myself.
